1Introduction
1.1 Brief description
Thank you for purchasing the Alpha OAE+ handheld Otoacoustic Emissions (OAE)Screener.
Note: This manual is your guide to the use and maintenance of Alpha OAE+. You must read it carefully before
using Alpha OAE+ for the first time.
Take particular note of the cleaning and maintenance instructions. Failure to use and maintain Alpha OAE+
correctly may void your warranty.
Alpha OAE+ is a fast, reliable, easy to use, and lightweight hearing screener. Alpha OAE+ provides for easy
navigation using its touchscreen function.
1.2 Docking station
Use only the power supplies specified in Technical Specifications, Power adapter.
Alpha OAE+ is supplied with a docking station that provides:
battery recharging
printing from a document printer
creating a PDF with test results
printing from a label printer
1.3 Printing
For printing instructions see Printing, 37.
Alpha OAE+
You can place Alpha OAE+ in the docking station and send reports to a PC. You can then print the reports from the PC. If you have an
optional label printer, it can be connected to the docking station and then you can print test results.
1.4 Intended Use
The Type 1077 device is indicated for use in the recording and automated analysis of human physiological data (screening auditory brainstem
responses and/or otoacoustic emissions) necessary for the diagnosis of auditory and hearing-related dis-orders.
Distortion Product Otoacoustic Emissions and Transient Evoked Otoacoustic Emissions:
The Type 1077 DPOAE module and TEOAE module can be used for patients of all ages, from children to adults, including infants and geriatric
patients. It is especially indicated for use in testing individuals for whom behavioral audiometric results are deemed unreliable, such as
infants, young children, and cognitively impaired adults.
Auditory Brainstem Response:
The Type 1077 ABR module is especially intended for infants from 34 weeks (gestational age) up to 6 months of age. When the device is used
to screen infants, they should be asleep or in a quiet state at the time of screening.
The device is intended for use by audiologists, ENTs and other healthcare professionals.
Note: There are no known contra-indications for use of Type 1077 device and accessories.
Note: The 1077 device comes in various configurations. The Alpha OAE+ device, which is a 1077 device, is only available in an OAE
configuration.
Note: Natus Medical Denmark ApS does not guarantee the accuracy of the test results or the tests themselves, if accessories other than those
supplied by Natus Medical Denmark ApS are used for this device (e.g., eartips).

1.5 Physical operating principle
Alpha OAE+ uses Distortion Product Otoacoustic Emissions (DPOAE) and TEOAE (Transiently Evoked Otoacoustic Emissions) technologies.
Otoacoustic Emissions measure cochlear mechanics and indicate whether the cochlea is functioning correctly or not. Emission strength
usually decreases with age or hearing impairment.

1.9 Warnings –Alpha OAE+
Warning: The following conditions or practices might present possible injury or danger to the patient and/or the user:
•Do not connect any external device (e.g., printer) to Alpha OAE+ during testing.
•If Alpha OAE+ is used during surgery, the probe and connectors must not touch conductive items including ground.
•Avoid accidental contact between connected but unused applied parts and other conductive parts including those connected to
protective earth.
•Do not use the instrument in the presence of flammable anesthetics (gases).
•The instrument and any device to be connected which has its own power supply should be turned off before any connections are
established.
•For safety reasons and due to effects on EMC, accessories connected to the equipment's outlet fittings must be identical to the type
supplied with the system.
•We recommend that the device should not be stacked with other equipment or placed in a poorly ventilated space as this may
affect the performance of the device. If it is stacked or placed adjacent to other equipment, make sure that the operation of the
device is not affected.
•Alpha OAE+ RF emissions are very low and are not likely to cause any interference in nearby electronic equipment, but negative
effect or loss of functionality of other local devices may occur if they are placed in close vicinity of Alpha OAE+.
•Make sure that the PC and the docking station are not within patient reach.
•When assembling an electro-medical system, the person carrying out the assembly must take into account that other connected
equipment which does not comply with the same safety requirements as this product may lead to a reduction in the overall safety
level of the system.
•Use only the power supplies specified in Technical Specifications, Power adapter.
•Alpha OAE+ must not be used during the application of:
–HF surgical devices
–cardiac pacemakers
–defibrillators
–other electrical stimulators
•Any PC connected to the device or used in the proximity of the patient must comply with IEC 60950-1:2005 and IEC 62368-1:2020.
•If you suspect your Alpha OAE+ handheld Screener might be defective, do not use it.
Caution: The following conditions or practices might present possible injury to the user or patient. Or there may be risk of damage to
the data or the device.
•Do not store or operate Alpha OAE+ at temperatures and humidity exceeding those stated in Technical Specifications, Operating
environment.
•No parts may be eaten, burnt, or in any other way used for purposes other than audiometry.
•Disposable accessories, such as eartips, should not be reused and must be replaced between patients to prevent cross-infection.
•This class of equipment is allowed in domestic establishments when used under the jurisdiction of a health care professional.
•Choking hazard! Do not leave eartips unsupervised within the reach of children.

4Preparing for testing
4.1 Preparing Alpha OAE+
•Follow the instructions in Getting Started with Alpha OAE+, 17.
•See Testing with Alpha OAE+, 23 on how to proceed with the specific tests.
4.2 Preparing the equipment
Every day before you start testing on patients, you should test the probe to make sure that it functions correctly. See Probe Test, 39.
Note:Insert only disinfected probe tips in the test cavity. See Cleaning the built-in test cavity, 47.
4.2.1 Preparing the probe for testing
Inspect the probe for deterioration (color changes, surface changes) of the reusable probe parts before every usage. If deterioration occurs,
contact your distributor.
4.2.2 Connecting the probe
Note:The probe socket is intended to connect the ear probe or ear coupler to Alpha OAE+ Screener. No other device may be
connected to this socket.
•Place Alpha OAE+ face down.
•Align the ridge on the probe plug with the notch in the grey-bordered socket on the top end of Alpha OAE+.
•Gently insert the probe plug into the probe socket. The plug does not require force to be inserted properly.
Disconnecting the probe
Note: Do not pull the plug by the cable when you disconnect the probe. Instead, pull the sleeve of the grey connector. Pulling on the cable can
damage the cable or connectors.
When disconnecting the plug, do not twist it. Instead, hold the sleeve of the plug and release it by pulling it straight out of the socket.
The probe will not be released if you pull anywhere else than on the sleeve of the plug.
4.3 Preparing the test environment
Physical environment
•Make sure that the test environment is as quiet as possible. The quieter the room the more accurate and quick your testing will be.
•Check that testing is not being performed under an air conditioner or in front of a fan or ventilator.
•Check that there are no mobile phones near, people talking etc.
